How I Built 4 Custom Apps in One Week to Solve My Real-Life Problems (With an AI Agent)

A developer built four custom applications in one week using an autonomous AI agent called Hermes to solve personal problems. The apps include a remote terminal with viewport rotation, a meditation PWA, a gym tracker, and a food diary with Gemini Vision AI integration.

We are always told that programming is a tool for problem-solving. But this week, I experienced this truth on a completely different level. Using my autonomous AI Agent Hermes , software development became my real-time, daily survival tool. Instead of searching for half-baked third-party apps, dealing with intrusive ads, or compromising on terrible mobile UX, I spent the last few days building four highly customized, production-grade applications to solve exact friction points in my daily life and for my family. Here is the story of how these four apps came to life. - Remote Terminal Defeating NoMachine's Screen Rotation Limit The Problem: I use NoMachine to control my main development PC remotely from my mobile phone. However, I ran into an incredibly frustrating limitation: there was absolutely no way to rotate the remote display viewport by 90 degrees to fit my mobile screen orientation properly. The Solution: Instead of giving up or hunting for obscure system-level workarounds, I built Remote Terminal. It is a lightweight remote execution client designed with a single killer feature: a built-in, hardware-accelerated 90-degree viewport rotation. Now, I can access and control my remote terminal rig perfectly, at the exact angle I need. - Tefila Meditation From Print Draft to Interactive PWA The Problem: I saw the draft of my wife's new meditation and prayer book right before it was sent to the physical print shop. I instantly realized that this content deserved an interactive, accessible digital life. The Solution: Within 24 hours, we built a generic, highly optimized book framework and compiled it as a Flutter Web PWA and Native Android App. - Autoplay-Safe Audio: Implemented a synchronous audio player engine to bypass aggressive mobile browser autoplay blocks. - Beautiful Visuals: Added native vector-animated CustomPaint widgets a flickering flame, flowing water, and rotating mandalas . - Offline-First Premium Model: Built a secure offline licensing system that unlocks chapters via secret coupon codes. - Live Proofreading Portal: Included a hidden, secure proofreader screen edit2026 so she can edit chapters and export updated Dart code directly from her phone - Deployed live on GitHub Pages: Check it out here. - My Personal Gym Companion The Problem: Most fitness and gym trackers on the app store are bloated with subscription popups, social feeds, and annoying ads. I just wanted a clean, fast way to log my workout routines and track my personal metrics while at the gym. The Solution: While heading out to my workout session, I scaffolded a lightweight, completely local Gym Companion app. It is entirely ad-free, runs completely offline, and lets me track my progress, sets, and health metrics with zero distraction. - Today: Visual Food Tracker With Gemini Vision AI Integration The Problem: Today, I visited my diabetes specialist. She requested that I start keeping a meticulous daily food diary to monitor my dietary habits. The thought of manually typing every meal, ingredient, and portion size into a clunky text-based app sounded exhausting. The Solution: I went home and, within a few hours, we built Food Tracker. It is an offline-first, visual-centric tracking app. I just released version 3.0: - Multi-Image Support: You can snap multiple photos per meal to track individual food items separately. - Smooth Carousel UI: On the home screen, meal cards turn into interactive swipeable carousels PageView so you can flip through the photos of your meal. - Google Gemini Vision AI Integration: I integrated Google's official google generative ai SDK using Gemini Flash . You take a photo, tap the "🪄 Smart AI Analysis" button, and the AI: - Identifies the food items and auto-updates the captions for each image. - Calculates estimated nutritional values calories, protein, carbs, and fats . - Automatically writes a detailed nutritional summary in the notes and suggests a cohesive title for the entire meal in Hebrew. The Takeaway: Software as a Personal Utility We are living in an era where the barrier between a raw idea and a working, compiled application has completely evaporated. When you pair your domain knowledge with a highly capable, autonomous AI agent, you stop being a mere consumer of software. You become a producer of your own tools, tailoring technology to fit your life, your health, and your family's needs in real-time. What is the next custom app you are going to build for yourself?
